Modular, six-axis-adjustable, concrete-pour form-structure system

ABSTRACT

A precision fabrication form system for preparing a poured-concrete (with upwardly projecting anchor bolts) footing for anchorably supporting the base of an elongate, upright, structural-frame column. The system includes a reversibly stackable plurality of independent, intercooperative, fabrication-form templates—grade, pedestal, base-plate, anchor-bolt and centerline—reversibly assembleable in a predetermined stack order above a prepared ground excavation into which concrete pouring to be associated with such a footing is to occur, certain ones of these templates being infinitely adjustable relative to one another and to the ground in both pre-pour and post-pour conditions to accommodate staged, precision, X-axis, Y-axis, Z-axis, and pitch, roll and yaw axes dispositions for the concrete and anchor bolts in such a footing.

BACKGROUND AND SUMMARY OF THE INVENTION

This invention pertains to a multi-axis-adjustable, high-precision formsystem for assisting in the fabrication of poured-concrete,ground-support footings, or pedestals, intended for supporting the lowerends (the bases) of elongate upright columns, such as columns that areto be, or may be, included in a structural frame which is to be definedby an array of plural, distributed, upright columns interconnected bytransverse beams. The terms “footing” and “pedestal” are used hereininterchangeably.

In a more specific sense, the invention proposes a high-precisionadjustability footing-fabrication form system which featuresindependent, six-axis, form-template adjustability—three linear, andthree rotational—and which employs, for each footing that is to befabricated, a vertically, reversibly stackable plurality of relativelysimple-configuration, independent, intercooperative form templates thatare freely reversibly assembleable in a predetermined, vertical stackorder designed to accommodate convenient and accurate, poured-concretefooting fabrication, and that offer versatile, relative-motion(including (a) within footing site template-to-template, and (b)footing-site-form-assembly-to-footing-site-form-assembly), infinitelypositionable, spatial-disposition adjustability features regarding thementioned linear (namely, X, Y and Z), and rotational (namely, pitch,roll and yaw), axes.

While, as will become apparent to those generally skilled in therelevant art, from a reading of the invention description which followsbelow herein, the form system of the present invention may be employedin the number of different column-support applications, it has beenfound to offer particularly utility in relation to assisting in theformation of poured-concrete anchoring footings/pedestals prepared forthe bases of columns that are to be employed in open, column-and-beamframe structures designed to receive and support plural, elongate,horizontal runs of pipe that may extend for long distances over andabove the ground in large oil and/or gas facilities. Accordingly, thepreferred and best mode embodiment of the invention is illustrated anddescribed herein generally in such a setting.

While various different, specific shapes of column-support footings mayreadily be handled by the form system of the present invention, thepreferred and best mode embodiment of it which is set forth herein ispresented, for illustration purposes, in relation to a footing stylethat includes a rebar-reinforced, stepped-lateral-dimension(larger-lateral-dimension, rectangular-block lower-section, andsmaller-lateral-dimension (diametral), cylindrical, upper-section),poured-concrete base, from the upper, flat, essentially horizontal andcircular surface of which upper base section there project plural,upwardly extending anchoring bolts to which appropriatelower-end-attached, column-base anchoring structure for an uprightcolumn may be secured.

Further describing, generally, certain features that are offered by thesystem of the present invention, the plural-form-template arrangement(mentioned above) which is employed during the creation of each footingis intended, through affording a capability for implementing thefeatured high-precision spatial adjustability of the invention, toenable, among other things, precise spatial-disposition formation andalignment associated with arranging a plurality of footings distributedin a planned array thereof intended to receive and support a plannedpopulation of columns, such as the above-mentioned array-plurality ofstructural-frame columns. In such a “column-plurality-array” context,and with respect to the important feature of precision spatialadjustability, the various templates which form part of the system ofthe present invention are relationally designed, as will be describedbelow herein, to accommodate, in a “fine-tuning” manner, the mentionedsix axes of independent adjustability, i.e., linear adjustability alongX, Y, and Z axes, and rotational adjustability about appropriate pitch,roll and yaw axes. This important, fine-tuning precision adjustabilityfeature—which I recognize to be very useful in many frame-column-supportapplications—is especially useful in the context of preparing footingsthat are to be employed as column-base supports in relation to thefabrication/assembly of a structural frame from initiallyprecision-manufactured column, beam and associated column/beamnodal-interconnect frame elements, such as those kinds ofstructural-frame elements which are illustrated and described in U.S.Pat. No. 6,837,016, U.S. Pat. No. 7,021,020, U.S. Patent ApplicationPublication No. 201210110947, and U.S. Patent Application PublicationNo. 2005/0066612.

So as to augment the herein provided, specific description andillustration of the present invention, the entire disclosure contents ofthese, four, prior-art documents are hereby incorporated herein byreference.

In accordance, therefore, with a preferred and best-mode embodiment ofthe invention, and discussed from one point of view, the inventionoffers a precision fabrication form system for assisting in preparing apoured-concrete (base)—with upwardly projecting anchor bolts—footing foranchorably supporting the lower end of an elongate, upright,structural-frame column—this system including a reversibly stackableplurality of independent, intercooperative, fabrication-form templatesthat are reversibly assembleable in a predetermined stack order above aprepared ground excavation into which concrete pouring to be associatedwith such a footing is to occur, with certain ones of these formtemplates being infinitely adjustable relative to one another, andrelative to the ground, in both pre-pour and post-pour conditions, toaccommodate staged, high-precision, X-axis, Y-axis, Z-axis, and pitch,roll and yaw axes, dispositions for the poured-concrete base and anchorbolts in such a footing. In the invention system descriptions that arepresented below herein, and while the following axial relationships donot necessarily need to be the case, the X-axis parallels thepitch-axis, the Y-axis parallels the roll-axis, and the Z-axis parallelsthe yaw-axis.

What may be thought of herein as the several, “relative adjustability”form templates include:

(a) a grade template restable on the ground immediately above, adjacent,and laterally surrounding a prepared ground excavation, defining agenerally horizontal support plane, and constructed for selective,independent, X-axis. Y-axis, Z-axis, pitch-axis and roll-axisadjustments relative to the ground and to such a prepared excavation, aswell as to adjacent footing sites;

(b) a pedestal template anchorably supportable in a vertically stackedmanner on the grade template's defined support plane, adapted to receiveand support a pedestal, upper-base-section, pour form (generallycylindrical herein), and adjustable independently and selectively alongX, Y axes, and about a yaw axis, relative to the grade template;

(c) a base-plate template supportable in a vertically stacked manner onthe pedestal template, adapted to receive and support, in a verticallystacked manner, an anchor-bolt template, and

(d) an anchor-bolt template placeable in a freely vertically receivedcondition relative to the base-plate template.

The form templates further include a temporary and intermediate-usecenterline template which is freely placeable, in a vertically stacked,and removeably nested, condition, on the base-plate template as aremovable precursor to placement, relative to the base-plate template,of the anchor-bolt template.

Yet another way of visualizing the invention is that it proposes aprecision, poured-concrete, column-ground-support footing-fabricationform system, for assisting in preparing, at each of a plurality ofspaced, column-support ground sites distributed in apredetermined-footprint ground array of such sites, a footing foranchorably supporting the lower end of an elongate, upright,structural-frame column which is to be included in a plural-column,plural-interconnecting-beam, structural frame constructed within thearray footprint, wherein each footing includes a concrete base andplural anchor bolts projecting upwardly therefrom, and precisionfabrication utilizing the system is enabled via system structuredesigned to accommodate precision, independent, X, Y, Z, pitch, roll andyaw axes spatial positioning of the base and anchor bolts associatedwith each such footing.

These and various other features and advantages that are offered by thepresent invention will become more fully apparent as the detaileddescription of it which follows below is read in conjunction with theaccompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Turning attention now to the drawings, and referring first of all toFIG. 1, indicated generally at 20 is a fragmentary portion of an open,rack-style, precision-fabricated, structural, column-and-beam frameextending over the ground, shown at 22, in relation to a predetermined,planned-footprint, plural-column array 24 of ground sites, such asground sites 25—this frame being designed to support runs of elongategas, oil, or other pipelines, such as the pipelines generally shownherein at 26. Included in frame 20, which, for illustration purposesherein, has been made in accordance with the precision frame-fabricationapproaches and components mentioned in the above-identified patents andpublished patent applications (whose full disclosures have beenincorporated herein by reference), are plural, elongate, uprightcolumns, such as columns 28, interconnected in the frame at different,common levels above the ground by horizontal beams, such as beams 30.These columns and beams join one another through precisely constructed,full-moment nodal connections, or nodal connection structures, 32 thathave also been made in accordance with the referenced patent andpatent-application disclosures. While illustrations of only a few ofthese connection structures 32 have been included in FIG. 1, in order tosimplify, somewhat, this drawing figure, it should be understood thatthey are present at every column-beam intersection.

Columns 28 are distributed over the ground in array 24 in apredetermined, designed, “row-and-column” pattern for frame 20. Thelower ends, or bases, of these columns are effectively “anchored to theground” at appropriately distributed and positioned anchor sites, suchas anchor sites 34, through poured-concrete footings, or pedestals, 36that reside, supported, in appropriately and respectively prepared,generally laterally square “footprint”, ground site excavations, such asexcavations 22 a, and column-attached, column foot plates 38 which siton the tops of these footings. More specifically, plates 38 are anchoredto the upper and upwardly facing, circular, horizontal surfaces 36 a ofthe upper base sections 36 b included in footings 36, which footingshave been fabricated utilizing the preferred and best-mode embodiment ofthe high-precision, multi-axis adjustable, plural-template form systemconstructed in accordance with the present invention—the structuralfeatures of which system will be described shortly.

As will become apparent, and while those skilled in the art recognizethat poured-concrete footings for supporting columns may take on anumber of different specific configurations, the present invention isillustrated herein in conjunction with the fabrication of footings thathave a configuration each including what may be thought of as astepped-lateral-dimension (i.e., possessing both (a)larger-lateral-dimension, and (b), connected smaller-lateral-dimensionsections), poured-concrete base possessing a rectangular-block-shapedlower section 36 c (defined by the above-described ground siteexcavations 22 a) having the larger lateral dimensions in the base, fromthe upper side of which lower section projects an upper, cylindricalsection 36 b (generally mentioned just above) having thesmaller-lateral-dimensions (a single, diametral dimension) in the base,with four, footing-included, partially concrete-embedded,column-foot-plate anchor, or anchoring, bolts 40 projecting upwardlyfrom the previously mentioned, circular, upper surface 36 a of the upperbase section.

To be noted especially at this point, is that the form system of thepresent invention, which offers the above-mentioned, high-precisionadjustability features (still to be more fully described) that allow forprecision fabrication and alignment of footings 36, accommodates quick,precise and convenient assembly of precision-fabricated frame 20.Precision adjustability of this form system is, as will become apparentto those skilled in the art, an important footing-fabrication offeringof this invention under all circumstances, i.e., notwithstanding theprecision nature, or not, of the ultimate assembly above of acolumn-supported structural frame. As will be more fully discussed laterherein, six-axis, precision adjustability performed during footingfabrication, in accordance with use of the form system of the presentinvention, is performed in relation to each of the two, commonlyaligned, orthogonal axis systems shown in FIG. 1 generally at 39(linear) and 41 (rotational).

With attention addressed generally now to the various system andassociated, other components that are presented in FIGS. 2 a-g: thecomponent shown at a is a conventionally assembled, appropriately shapedpedestal rebar structure 42 which is employed as an embedded,reinforcing, core armature in the poured-concrete base for apedestal/footing: the component shown at b is a double-open-ended,cylindrical pedestal pour form 44, made, for example, of any suitableflexible material, such as a flexible plastic material, which form,during pedestal fabrication, circumsurrounds the upper portion of thejust-above-described pedestal rebar structure to define, and accommodatethe pour-formation of, the generally cylindrical,smaller-lateral-dimension, upper section 36 b of a pedestal/footingbase; the component pictured at c is a grade template 46 which forms alower part of the form structure of the present invention, and whichincludes spaced, substantially parallel, elongate rails 46 a that definewhat is referred to herein as a support plane 46 b which is illustrated,only in FIG. 10, fragmentarily by a dash-dot line; the componentillustrated at d is a pedestal template 48 which is designed to sit, aswill shortly be described, on the grade template's defined support plane46 b, and which also forms part of the form structure of the presentinvention; the component appearing at e is a base-plate template 50—alsoa component which forms part of the form structure of the invention, andspecifically a part which is designed to be supported, as will beexplained below, on top of the pedestal template; and the componentsshown at f and g—also components that are parts of the form structure ofthe present invention—are, respectively, f, a temporarily, andintermediately, employable, flat-plate, square, centerline template 52,which includes a central, orthogonal-crossed line-pair mark, orcross-mark, 52 a, adapted to be removeably and nestably received, for ashort period of time, within a complementary receiving portion which isprovided on top of the base-plate template, and g, an anchor-bolttemplate 54 having an open, square, upper portion 54 a which is adaptedalso to be removeably and nestably, complementarily seated, as willlater be explained, at the same location just mentioned on top of thebase-plate template following removal therefrom of the earlier,temporarily employed centerline template.

For a reason which will be explained later, upper square portion 54 a inanchor-bolt template 54 is temporarily attached, adjacent its fourcorners, by pairs of later-discardable, upper and lower, removableclamping bolts (not specifically illustrated), to four (a number chosenfor illustration herein), elongate, downwardly extending, threaded, andpreviously mentioned anchor bolts 40, the upper ends of which projectslightly above portion 54 a through upwardly facing, “corner-prepared”(in template portion 54 a and not specifically illustrated), clearanceholes.

Templates 46, 48, 50, 52, 54, as just indicated above in other words,collectively make up the precision-fabrication form system of thepresent invention. These templates are also referred to herein togetheras a reversibly stackable (in a defined stack order) and assembleableplurality of independent, intercooperative, fabrication-form templates.

As will become more fully evident to those skilled in the art fromviewing FIGS. 4-16, inclusive, herein, the several, differentlyconfigured templates just mentioned in relation to FIG. 2, whichtemplates essentially define the totality of the form structure of thepresent invention, are suitably made, variously, from conventionallyavailable (preferably steel) angle-iron stock, flat bar and plate stock,rectangular-tubular cross-section stock, etc., with these conventionalstock materials appropriately joined, as by welding, to have theappropriate shapes and sizes suitable for practice of the invention.Another matter regarding these template structures which will beappreciated by those generally skilled in the relevant art is that theirrespective sizes may be chosen appropriately to accommodate differentfooting-fabrication applications, and to relate them, in size,one-to-another, so that they will function correctly duringhigh-precision-adjustability footing fabrication. In these respects,regarding the structures of the form templates just described and seenin FIG. 2, it should be noted that the precise details of these templatecomponents, except insofar as they need to relate to one another asdescribed and illustrated herein, are not critical, and do not form anypart of the present invention.

More about these templates, including further details regarding theirrespective constructions and functional features, and about the formsystem of the present invention which they collectively andcollaboratively define, is now presented in relation (1) to the“earlier-stage to later-stage” footing-fabrication conditions that arepresented collectively in a unified, perspective fashion in FIG. 3, andthere in a manner, as expressed above, “stage-progressing” in thisfigure toward the viewer, and (2) to step-by-step, “system-in-use”discussions focusing on what is pictured step-sequentially in FIGS.4-17, inclusive. FIGS. 4-17, inclusive, fully illustrate how, viaemployment of the form system of the invention, the included formtemplates, in a defined order of stacking, and eventual unstacking,function to assist in the fabrication of a poured-concrete (withupwardly projecting/extending anchor bolts) column-base support footing.

FIG. 4, viewed along with FIG. 10 (and to some extent, with FIGS. 3-9,inclusive, and FIGS. 11-17, inclusive), illustrates, in adrawing-shape-idealized way, one of the previously-referred-toground-site excavations 22 a, dug, during a preliminaryfooting-fabrication step, which is the specific step pictured in FIG. 4,to have a suitable depth, and herein an appropriately sized, square,lateral footprint, as determined by the planner(s) of frame structure 20in relation to load-carrying requirements for this frame. The lateraland depth dimensions of site excavation 22 a are determined inaccordance with the particular frame-design application, and do not formany part of the present invention. As was mentioned earlier herein, andas will become apparent from descriptive text which follows below, eachexcavation site 22 a effectively defines the shape and size of thelarger-dimension, lower base section 36 c in each footing 36.

FIG. 5 pictures the next footing-fabrication step which involves theinsertion into excavation 22 a of previously described pedestal rebarstructure 42. With reference made to FIG. 10 along with FIG. 5, theherein, designer-selected, relative vertical dimensions of this rebarstructure and of the depth of site excavation 22 a are clearly seen.This relationship, of course, is one of designer choice, with theupwardly extending size of the pedestal rebar structure designed tofunction appropriately as a central, core armature for a poured-concretepedestal base. The upper reaches of the rebar structure will, of course,extend embeddedly within the upper, smaller lateral dimension (hereindiameter) cylindrical section 36 b of a footing 36.

FIG. 6 pictures placement on the ground, above, adjacent, andsurrounding what is shown in FIG. 5, of a grade template 46. Thistemplate, which herein is rectangular in “footprint” configuration, andhere, one should also consult FIG. 10, in addition to includingpreviously mentioned, spaced, elongate and substantially parallel rails46 a that define previously mentioned support plane 46 b, additionallyincludes elongate, spaced, upper cross rails 46 c which parallel oneanother and which are affixed, as by welding, to the upper surfaces, andadjacent the opposite ends, of rails 46 a, as can be seen. Adjustablyand threadedly attached in a manner extending threadedly through, andadjacent, opposite ends of rails 46 c, laterally outwardly of theopposite ends of rails 46 a, are elongate, generally vertical, threaded,screw-adjustable legs, such as legs 46 d, the lower ends of which,positioned below rails 46 a, 46 c, carry ground-engaging feet, or pads,such as pads 46 e.

FIG. 6 further illustrates, comprehensively, in relation to the thereinpictured, single site excavation (and see also FIG. 1, and FIG. 3 withrespect to array 24 which includes, as seen there in FIG. 3, plural,array-related site excavations) the relevant, precision-adjustment X, Yand Z linear axes—shown by double-ended, linear arrows labeled X, Y andZ—and additionally, the relevant, precision-adjustment pitch, roll andyaw rotational axes, which rotational axes are shown, respectively, bothby dash-dot axis lines, and by double-ended, curved,rotational-directions arrows, 56, 58, 60. Presentations of one or moreof these axes in other drawing views herein are limited to illustratingthere the specific precision adjustment, or adjustments, and theassociated precision-adjustment axis, or axes, best related to theseother views. FIG. 1, as mentioned earlier, includes a presentation ofall six of these axes.

A grade template, such as template 46 will typically be put into placewith what may be thought of as simply “eyeballed”, but not precision,though nevertheless “closely proper”, X, Y and Z orientations within acolumn-plurality-array, such as array 24. As will become apparent, suchless-than-precision, X, Y and Z “eyeballing” associated with agrade-frame positioning relative to a site excavation is all that isnecessary in the practice of the present invention with regard to how agrade template is initially put into place. However, in other waysbeyond especially such X and Y, general eyeball positioning, the gradetemplate form ultimately furnishes, essentially via defined supportplane 46 b, several of the important, independent,precision-adjustability features that characterize the form-templatesystem of the invention, and specifically furnishes precisionpitch-axis, roll-axis and Z-axis adjustability.

Accordingly, in preparing, relative to what is pictured in FIG. 6, forultimate, final concrete-pouring footing fabrication, and as will bemore fully explained later herein, appropriate precision screwadjustments are made in legs 46 d and their carried foot pads 46 e toadjust for proper pitch, roll and Z axes dispositions for the associatedgrade template, and in particular, for the grade template's definedsupport plane 46 b, and thereby for other, overhead-supported templates,relative to the ground and to the associated site excavation, andadditionally for the in-place pedestal rebar structure. Any appropriate,conventional precision leveling, angling, aligning, etc. technique(s),such as those employing surveying transits, and other surveying-qualitydevices, such as laser-beam devices, may be employed at the appropriatetime(s) to establish suitable, confirmed “end points” for suchprecision, pitch-, roll-, and Z-axis adjustments.

FIG. 7 illustrates the next step involved in the employment of thetemplate system of the present invention, and specifically picturesplacement of pedestal template 48 for limited-range, multi-direction,“in-support-plane-46 b” sliding, for precision, independent X-axis,Y-axis and yaw-axis adjustments, on rails 46 a in grade template 46. Seehere also FIG. 10. Template 48, as constructed herein, and as wasmentioned briefly above with respect to the constructions, generally, ofthe several frame components shown in FIG. 2, is formed of plural,suitably joined, elongate, bar- and angle-iron-stock pieces, as seen inFIG. 7 (as well as in FIGS. 2 and 10). It includes spaced, parallel,angle-iron rails 48 a that sit slidably, directly and removeably on thetop surfaces of rails 46 a in the grade template, and thus effectivelyon support plane 46 b, and further includes, suitably joined to anddisposed between rails 48 a, a central, square-open-box, window assembly48 b having spaced, opposite, parallel sides, and which assembly isdesigned, as will be described more fully shortly with respect to alater, fabrication-assistance step pictured in FIG. 8, to receive andsupport, removeably, vertically slidably, and generally freely, one of acylindrical, concrete-pour, pedestal form 44, such as is seen in FIG. 2.

Regarding the condition described above as limited-range,multi-direction. “in-support-plane-46 b” slidable seating of template 48on template 46, while this condition may be accommodated in a number ofdifferent conventional ways, it is enabled herein, in one of these ways,by the provision of an appropriate plurality (such as four) ofX-axis-adjustable, Y-axis-adjustable and yaw-axis-adjustable,collaborating pin and pin-receiving-opening arrangements. Sucharrangements, which are entirely conventional in nature, and which arenot specifically shown or detailed in the present drawings, are providedat appropriate, contact-interface locations between templates 46, 48,and are located, as a collaborating set of such arrangements, relativelycentrally regarding the “lateral footprint” of grade template 46. Forexample, in connection with these non-pictured pin, etc. arrangements,rails 48 a herein carry short, downwardly projecting pins that extend,when template 48 is properly seated on template 46, withuser-predetermined, all-around clearances through generally verticallyaligned, circular openings provided in rails 46 a.

These pin, etc. arrangements, as those skilled in the art will clearlyrecognize, enable limited, in-support-plane-46 b slidable motion of thepedestal template initially loosely, and generally centrally, as shownin FIG. 7, on top of rails 46 a, with the pin and pin-receiving-openingarrangements then allowing for appropriate, limited, precision X-axis,precision Y-axis, and precision yaw-axis (60) relative sliding motionsand angular adjustments to take place between the pedestal template andthe underlying grade template, specifically in a manner accommodatingprecision X-, Y-, and yaw-axis positionings of template 48 relative (a)to the immediately associated site excavation 22 a, (b) to its receivedpedestal rebar structure 42, and (c) to other site excavations 22 a inarray 24. When such precision adjustments have ultimately beenmade—adjustments that will be made, and are still to be more fullydescribed, at and in relation to a later fabrication-preparation stagepictured in the drawings, templates 46, 48 are then releasably lockedtogether in any suitable manner, as by conventional, releasableclamping, in order to function as a stabilized, unitary structure duringsubsequent concrete pouring.

FIG. 8, as was just mentioned briefly above, illustrates a further stepin the footing fabrication-assisting practice which is now beingdescribed, and specifically shows that a concrete-pour pedestal form 44has been lowered, slidably and freely, through the square windowfurnished in the central, square-open-box, window assembly 48 b intemplate 48, to surround an upper portion of pedestal rebar structure42. Preferably, the inside, transverse dimensions of “square” assembly48 b, i.e., the dimensions existing between the four components whichform its opposite, parallel sides, are substantially equal, and justslightly greater than the outside diameter of form 44—a condition whichaccommodates the mentioned free, slidable reception of the pedestal formto have the disposition shown for it relative to templates 46, 48pictured in FIG. 8. In terms of supporting form 44 effectively by windowassembly 48 b in the template 48, this is accomplished herein by theprovision, at several (such as four) locations adjacent the upper rim ofform 44, of small, outwardly projecting tabs (not shown) which come torest on the upper surfaces existing in the four, component-formed sidesof assembly 48 b. This arrangement herein positions the top of form 44at about the level of the top of template 48 (see also FIG. 10).

FIG. 9 in the drawings illustrates what happens next, and namely, thatbase-plate template 50, which includes four, small, “corner”, supportfeet 50 a, becomes appropriately seated via these feet—preferablylaterally fixedly and conventionally pin-located through conventionalpin-and-hole registry structure (not shown) associated with these feetand with underlying pedestal template 48—on top of two of the oppositeside components that form opposite sides of assembly 48 b in thepedestal template. In this pin-registered condition, X-axis, Y-axis, andyaw-axis precision adjustments made in pedestal 48 are communicateddirectly and commonly to the base-plate template.

The four elongate components, clearly seen in FIG. 9, which componentsmake up a portion of the base-plate template, define herein a square,central, upwardly facing, open well structure 50 b. This well structure,whose two functions will be described immediately below, resides in acondition spaced somewhat above the top of assembly 48 b in pedestaltemplate 48 (here, see also FIG. 10).

The next two stages of pre-concrete pouring fabrication assistance areillustrated, respectively, in FIGS. 11 and 12.

In FIG. 11, with base-plate template 50 in place as just described,centerline template 52 is complementarily and nestably seated inwell-structure 50 b—this centerline template bearing on its uppersurface, the previously mentioned, central, orthogonal-crossed-line-pairmark, or cross-mark, 52 a. With the centerline template in place, andusing (a) the just-mentioned cross-mark 52 a as a central and key datumreference for alignments and adjustments, along with (b) selected,relevant, precision alignment instruments and devices, such as thoseidentified representationally above, all, final, pre-concrete-pouring,precision X-axis, Y-axis, Z-axis, pitch-axis, roll-axis, and yaw-axisadjustments are made. Such adjustments are specifically performedthrough the making of relative, X, Y, and Z linear, and pitch, roll, andyaw rotational, positional motions accommodated, respectively, and asexplained above, (1) by the legs and associated foot pads in gradetemplate 46 to control the disposition in space, and specificallyrelative to the ground and to a site excavation 22 a, of support plane46 b (see again specifically FIG. 10), and thereby to furnish precisionpitch-axis, roll-axis and Z-axis adjustments, and (2), relativelybetween templates 48 and 46 to furnish precision X-axis, Y-axis, andyaw-axis adjustments. These adjustments are made both on (1) aper-footing-site/ground-site basis relative to the site-associatedexcavation 22 a, and (2) as well on aninter-footing-site/inter-ground-site basis within and throughout array24.

These adjustments fundamentally, and with high precision, correctlyposition the various components that are shown in FIG. 11 with respectto the ground at that location, and additionally, and considering thefact that before concrete pouring takes place, similar precisionadjustments are made at all other ground-site excavations in array 24,prepare all of the relevantly associated pre-pour footing locations withprecise, inter-site alignment.

Following the making of such precision adjustments, the centerlinetemplate is removed from the base-plate template, and in its place, theanchor bolt template is installed, as illustrated in FIG. 12. As can beseen here, with this anchor-bolt template so-installed, its upperportion 54 a seats, complementarily, within the previously mentionedwell structure 50 b provided in base-plate template 50, with anchorbolts 40 (two of which are shown in this figure) now properly positionedin downwardly extending positions within the confines of pedestal form44—adjacent the corners of the upper portion of pedestal rebar structure42.

Thus, in the preparations for assistance in precision footingfabrication, and related concrete pouring to create, in conjunction withanchor bolts 40, an associated, poured-concrete footing base, thevertical stack arrangement, or order, established for uses of theseveral form templates of the invention, progressing upwardly from theground, is the grade template, the pedestal template, the base-platetemplate, the centerline template, and, once the centerline template hasserved its temporary purpose during precision adjusting and has beenremoved from the underlying, three-template stack, the anchor-bolttemplate.

FIG. 13 next illustrates the result of concrete pouring, an action whichis readily accommodated by the openness of the assembled template-formstructures, with this pouring activity resulting in a poured-concretefooting having the appropriate, rectangular-block-like lower basesection 36 c, and the appropriate, upper, cylindrical base section 36 b.As was suggested earlier herein, the form-template structure of theinvention, as seen in FIG. 11, not only has, just before concretepouring, accommodated multi-axis precision adjustments as described,but, as seen in FIG. 13, and notwithstanding the fact that centerlinetemplate 52 has, at this stage, been removed, also permitspost-concrete-pouring, final, fine adjustments, if any are deemednecessary, before the poured concrete has solidified and stabilized.

FIG. 14 illustrates that the base-plate template has been removedfollowing concrete pouring, with such removal providing good clearancefor surface finishing of the top surface 36 a of the cylindrical upperbase section of a poured footing. At about this same time, and certainlywhen the poured concrete has “set” sufficiently, the cylindricalpedestal form 44 is removed. So also now removed, and here see FIG. 15,is pedestal template 48.

From the conditions shown in FIG. 15, grade template 46 is removed toleave in place what is shown in FIG. 16. And now considering therelationship between conditions shown in FIGS. 16 and 17, the upper,square portion, 54 a, in the anchor-bolt template, is removed, toexpose, as seen particularly in FIG. 17, upwardly extending portions(above footing surface 36 a) of anchor bolts 40.

At this juncture, it is appropriate to direct attention specifically tothe distributed-fashion, progressive-stage,fabrication-assistance-sequence illustration presented in FIG. 3, whichshows two rows, including six-each ground sites in what may be thoughtof as matching pairs of footing-fabrication preparation, and finally,ultimate completion, conditions 62, 64, 66, 68, 70, 72. The conditionsshown at 62 relate to what is shown in previously discussed FIG. 4.Those shown at 64 and at 66 are alike, and relate to what is pictured inFIG. 5. The two shown at 68 relate to what appears in FIG. 6. Thematching conditions shown at 70 relate to what is seen in FIG. 12. Thelast two site conditions shown at 72 relate to the illustration of FIG.17.

A preferred and best-mode embodiment of the invention has thus now beenfully described in relation to associated drawing illustrations. Theform-template system of the invention clearly offers decided advantagesin the precision fabrications of column-support footings, and especiallyin the precision fabrications, alignments, and spatial dispositions ofsuch footings in an array, such as illustrated array 24. The templatecomponents of the invention are relatively simple and inexpensive; theyare very easily and intuitively employable; and their “verticalopenness” readily accommodates easy, unobstructed concrete pouring.

Useful variations and modifications are certainly possible which willcome to the minds of those skilled in the relevant art, and accordingly,all such variations and modifications are expected to be treated ascoming within the scope and spirit of the invention.
